Brittany has 8+ hiking trails covered in this guide, led by GR34 Emerald Coast Section: Saint-Malo to Cap Fréhel, GR34 Pink Granite Coast: Perros-Guirec to Trébeurden and Belle-Île Coastal Circuit (GR340). Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Brittany (Breizh) is France's westernmost peninsula — a Celtic heartland thrust into the Atlantic where granite cliffs, prehistoric megaliths, medieval walled cities, and 2,800 kilometres of coastline combine into one of Europe's most distinctive travel destinations.

Local hazards

What to watch out for on the trail.

Medium

Hazard: Tidal cut-offs: several sections of the GR34 cross tidal zones that are cut off at high tide — always carry a tide table and check before setting out

Medium

Hazard: Cliff edges: unstable rock on headlands at Pointe du Raz, Cap Fréhel, and Crozon Peninsula — stay strictly on marked paths

Medium

Hazard: Atlantic weather: conditions can change from calm to storm in under 2 hours, particularly on the Finistère coast — check Météo-France (meteofrance.fr) before any cliff walk

Medium

Hazard: Limited water on cliff paths: few potable water sources between towns; carry at least 1.5L for half-day walks

Medium

Hazard: Hunting (la chasse): October–January in inland forests — wear high-visibility colours when walking in woodland outside marked tourist paths
